Thanks Brenner!

The ESC is located just behind a air inlet at the front so it has got cooling from two directions. I am using the Mezon 95 Opto light. The temperature of the ESC with the Pyro is a bit higher than when I used the Pletty Advance. From the sound level the ESC is more happy with the Pyro motor. It is dead quiet. When used with the Advance I get a lot of frequency noise from the motor. It is like the motor amplifies the frequencies like a loud speaker.

I have started to focus a bit more on the cooling of motors and ESC as I have had some issues in the past with overheating ESCs and motors.

The picture was taken while the paint was still wet and reason for the black and flat colours.

Br,
